Abstract: Main objective of the thesis is to study the numerical modeling of wind loads on high-rise structures using computational fluid dynamics. Simulation of a turbulent boundary layer over tall building models was carried out at the Supercomputing and Visualization Unit, the National University of Singapore, using FLUENT 6.1.18. Turbulence was introduced at the inlet through a parallel auxiliary simulation and the computation of the flow advanced in time using large eddy simulation with an RNG-based subgrid-scale viscosity model. Wind velocities at different locations and wind pressures on the buildinga??s faces were recorded, subsequently the flow characteristics were investigated and the force and moment spectra deduced. The results were compared with data from earlier wind tunnel experiments carried out at Virginia Polytechnic Institute and State University. It is concluded that numerical wind tests on tall structures are a viable alternative to the conventional tests in wind tunnels.
